When updating GeneWeb, make sure that bases are properly saved to recover them in the new version.Moving mybase.gwb folders from a version to another may work, but is not guaranteed.

The last version GeneWeb v7.00-alpha in particular isn’t backward compatible.You must inevitably extract a GeneWeb file (.gw) of your database from your old GeneWeb version and import it to the new one (do not copy/paste or move /bases directory).

** An alpha version of GeneWeb 6.08 and 7 has been announced and released in September 2014.The 7.00 alpha version adds the management of events. The second database format (gwc2/ged2gwb2) is not working in this version.
